碳二体系络合吸收剂的研究

Study on the Complexation Absorbent for Ethane/Ethylene

通过测定乙烯 /乙烷在含氮基团络合亚铜体系中的无限稀释相对挥发度 ,研究了基团碱度、配比数及稀释剂对吸收剂选择能力和稳定性的影响。实验表明 ,兼顾稳定性和选择能力 ,含氮基团与亚铜的最佳配比为 3～4 ;稀释剂的极性越大 ,吸收剂的稳定性越好 ;

Through determination of the infinite relative volatility for ethane/ethylene by means of gas stripping method, the ability of the cuprous halide amine to separate ethane/ethylene is evaluated and the factors influencing the stability of the cuprous halide amine such as the basicity of ligand,diluters,ratios are studied. As the experiments shown,the best ratio for amine ligand and cuprous halide can be between 4∶1 and 3∶1;as the polarity of diluters increases,the stability of the absorbent increases and the ability to complex with ethylene decreases;the stronger basic ligand can make full use of its stabilizing function when the ratio is relatively low.
